What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object above the ground.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is the formula for calculating Potential Energy?

Back

Front

What factors affect Potential Energy?

Back

Potential Energy depends on height and mass.

Front

What is Elastic Energy?

Back

Elastic Energy is the potential energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the formula for calculating Kinetic Energy?

Back

Front

How does height affect Potential Energy?

Back

As the height of an object increases, its Potential Energy increases, assuming mass remains constant.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy increases with an increase in mass, assuming velocity remains constant.

Front

What happens to Kinetic Energy when speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What is an example of Potential Energy?

Back

An example of Potential Energy is an apple sitting on the edge of a table.
